The Byrds of Paradise, on ABC
IMDb; TV Tango; Wikipedia
Um, so there was this teacher named Sam Byrd (Timothy Busfield). After his wife died, he moved from Connecticut to Hawaii with his kids, Harry (Seth Green), Franny (Jennifer Love Hewitt), and Zeke. Sam got a job as headmaster of a private school, there. Which his kids attended. So basically, the family had to get used to living in a new environment while also dealing with the loss of wife & mother. I don't remember the show well, but it was kind of quirky, and of course Hawaii's always nice to look at. It was cool seeing them interact with the locals. I'd really like to see it again someday so I could write a proper review.
